Is it possible to have 4 guitarists in a band?

Yes, it is possible to have 4 guitarists in a band. Many bands have had this lineup, including The Allman Brothers Band, ZZ Top, and Lynyrd Skynyrd. This lineup can create a powerful and unique sound, as it allows for a variety of different guitar textures and sounds. Additionally, it can allow for more experimentation and improvisation, as each guitarist can bring their own ideas to the table. However, it can also be difficult to manage four guitars in a live setting, as each guitarist will need to be aware of the others' parts and make sure they are not drowning each other out.
